Here's the Radeon HD 6990 up close. The HD 6990 is AMD's new dual-GPU graphics card that extends the performance leadership held by Radeon HD 5970. The pictures put rest to some speculation surrounding the cooler design. It now appears that the cooler design is similar to that of the GeForce GTX 295 single-PCB, as far as air-flow is concerned. A single long PCB holds two GPU systems on either sides, a centrally-located blower pushes air on either sides. The exhaust from one GPU is sent out of the case, while that from the other is pushed out of the card from its rear portion.

The Radeon HD 6990 uses two 40 nm Cayman GPUs, it packs a total of 3072 stream processors, and 4096 MB of memory between the two GPU systems. It also features a new kind of display output that consists of one dual-link DVI and four mini-DP 1.2. Power is drawn in from one 6-pin and an 8-pin PCIe connector. The card can pair with another of its kind for 4-GPU CrossFireX. It is expected to be released a little later in this quarter.

A monolith. With a red circle in the center. With the Radeon logo. Perfect!
Although it has a 6+8-pin config, you can see the shroud design left space in the 6-pin so that there could be an 8-pin...instead of a 6-pin.
And Quad crossifre seems enough.
